Micropenis Associated with Decreased Nocturnal Erectile Activity

In this article, we will examine a 2005 study published in the "International journal of impotence research", named "Effect of penile size on nocturnal erections: evaluation with NPTR testing with men having micropenis".

The abstract of the study first explains that the published literature has conflicting evidence regarding the sexual function in hypogonadal men with the micro-penis condition.

Purpose of the study was to evaluate the erectile functon of such men, by measuring "nocturnal penile tumescence and rigidity testing (NPTR)" and comparing their results with the scores achieved by young men with an average penile length.

Patient Profile

The researchers enrolled a total of 15 young males (17 to 30 years old), all with a micropenis. Their mean stretched penile length was found to be 6.81.6 cm (min: 3.6 cm max: 7.8 cm).

Control Group

The control group was comprised of 22 potent and normal penile sized male young individuals (23 to 29 years old).

Method

Both groups completed three sessions of consecutive nights with the RigiScan Plus device fixed to their penis.

Results
The study concludes that men with a micropenis "are associated with decreased nocturnal erectile activity".

According to wikipedia's article on "Nocturnal penile tumescence", this finding may be translated to higher incidences of physiological erectile dysfunction in men with micropenis.

Here's the abstract of the study:

"There has been conflicting opinions in the literature regarding sexual function in hypogonadal men with micropenis. In this study we aimed to evaluate erectile function in hypogonadal men with micropenis by nocturnal penile tumescence and rigidity testing (NPTR) and compared the results with young potent normal penile sized men. A total of 15 men (ages 17–30 y) defined having a micropenis with a stretched penile length of less than 9.3 cm were constituted the study group. Mean stretched penile length was 6.8plusminus1.6 cm (range 3.6–7.8 cm). Karyotype analysis showed 46XY in all cases. Control group included 22 potent and normal penile sized men (23–29 y). All subjects completed three sessions of consecutive nights using the RigiScan Plus device. Comparison of the results of NPTR of control group with study group revealed that number and duration of erectile episodes (P<0.001), duration of tip rigidity >60% (P<0.01), TAU tip and TAU base (P=0.001), and RAU base (P=0.01) were found to be significantly lower in men with micropenis. In conclusion, our study showed that men with micropenis are associated with decreased nocturnal erectile activity."
